Version: 3.0.2
OS: Gentoo
My Bacula director recently decided that it needs to crash randomly after doing
backups. It mostly happens when backups run from the schedule, but sometimes
happens when I run backups manually. This suddenly started happening on August
11. Up to that point I had been running 3.0.1 for about a month just fine and
without problems. I upgraded to 3.0.2 to see if it would fix the problem, but
it didn't.
I have tried rebuilding the MySQL database as well as re-compiling in case I
missed something, but neither of those ideas worked either.
Any ideas that people can shed on the subject would be very helpful. It looks
like libbac.so.1 is causing some sort of issue. Using gdb, I got the following
output:
Program received signal SIGSEGV, Segmentation fault.
